Genioplasty with morselized autologous bone graft / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To investigate a new method of genioplasty for treatment of a prominent mandibular angle with mandibular malformation.</p><p><b>METHODS</b>According to the different types of the mandible, the prominent mandibular angle was grinded with the masseter muscle kept intact. Autologous micromorselized bone of the grinded mandibular angle was collected and implanted into the chin for augmentation mentoplasty, and the chin was fixed with gypsum after operation.</p><p><b>RESULTS</b>Fifteen patients receiving the surgery were followed up for 6 -12 months, and satisfactory effects were achieved in 12 patients. One patient requested modification of the shape of the chin 10 days after the operation, and another two sustained chin distortion due to external forces and underwent subsequent shape adjustment of the chin.</p><p><b>CONCLUSION</b>The procedure described avoids graft rejection and causes less complications for genioplasty with easy moulding and satisfactory outcome.</p>
